Perhaps you should try some spelling variations:
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"defined using algorithm" » "defined cosine algorithm" (Expand Search), "designed using algorithm" (Expand Search)
"data tracking algorithm" » "radar tracking algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data tracking algorithm\") OR (\"defined using algorithm\"))) OR (\"element method algorithm\"))~".
• Removing quotes may allow a broader search: (((( data tracking algorithm ) OR ( defined using algorithm ))) OR ( element method algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("data tracking algorithm") OR ("defined using algorithm"))) OR ("element method algorithm"))*.
